Assuming you are going to build a membership website I suggest the following path :
- In addition to learning HTML, CSS and JavaScript learn a backend language like NodeJS, Python or Ruby.
- Learn how to work with databases - Either SQL or NoSQL. But I will recommend learning internals of a NoSQL provider like mongo, couchdb etc.
- Learn a frontend framework like Foundation or Bootstrap. If you are not into designing it will give you a head start.
- Wordpress is good, but for serious projects I will suggest building something yourself. Also you will keep full control over your project this way.
- Learn how to integrate payment processors into your apps.
I don't have any experience with vr or gaming, so can't comment on that.
Good Luck!
